I didn't use a mortar under my bathroom floor, but used roofing nails to put down the backerboard. I did this in the fall of 2006 and have not had any problems since, what problems should I expect since I didn't do this according to your specs?

Also, how does a flooring company complete a tiled floor in two days? Based on your directions it would be a 3 day minimum job. Are you just being extra cautious or is this flooring company not performing quality work? Thanks!
